most definitely a must have. I didn't have covers for my first pair and before the season was over, they were worn almost through. You gotta have covers on your cleats, I barely walked in mine and they're shot causing me to replace the cleat.

I have chewed up several pairs of Look Keo cleats simply by walking around in my bike shoes. The NAshbar cleat covers are sturdy and durable, but I found them hard to slip over the cleats. The cleat covers also need a shower curtain hook to keep them clipped together when they are not in use.

Made for KEO Look cleats; they currently fit well, however I am not sure if they will stretch out over time... So far this is great since I ride to an event and then walk around at local events without worrying about getting rocks, mud, or grass in my cleats, or worry about wearing out my cleats walking around.

Wet wood and smooth concrete are like ice when wearing regular cleats. These covers correct the problem. They are quiet to walk in and will prevent your cleats from getting filed down when walking on concrete or asphalt. The little rubber pads on my old cleats lasted about a month if I had to walk more than a few feet on a rough surface. I prefer the teflon Keo cleats when I am on the bike and these covers make them safe to walk in when off the bike.
